多変量解析による臨床化学検査データの生理的変動因子に関する研究 : 奈良医大学生のデータを用いて

Abstract

Effects of physiological and habitual factors on clinical chemical laboratory data were studied by multivariate analysis with data obtained from students of Nara Medical Uuiversity. The results are as follows. Serum ALP, GPT, ChE, UA and Cr levels were higher in male than in female subjects, whereas HDLch level was higher in females. This elevation of HDLch in female subjects is suggested to be due to estrogen. We also made a gender discriminant function with five parameters, ALP, ChE, HDLch, UA and Cr, which was able to discriminate prospectively 92% of male and 100% of female subjects. Habitual exercise or sports were likely to raise ALP and γ GTP levels. Habitual drinking was likely to raise GOT, LDH, γ GTP and HDLch levels, as indicated in previous reports. HDLch was elevated in subjects with rice-restricted diets and much confectionery consump- tion. The high fat content in confectionery may be associated with elevation of HDLch. Body height and weight were strongly correlated with UA and Cr.
